Descripción técnica

OctoPrint provides a web interface for controlling consumer 3D printers. From 2.0.0rc1 until 2.0.0rc7, an authenticated user can supply a crafted default port or baudrate through a connect request to the bundled Serial Connector plugin. OctoPrint persists these values in printerConnection.preferred.parameters.port or printerConnection.preferred.parameters.baudrate and renders them as HTML when another user views the saved connection parameters, allowing script execution in that user's browser and actions within the user's OctoPrint access. This issue is fixed in version 2.0.0rc7.

——0In Eclipse Langium versions 3.0.0 and later, the langium-sprotty package does not HTML-escape diagnostic messages before rendering them in the default hover popup provided by `addHoverPopupHandler`. If a Langium grammar allows cross-reference text to contain HTML markup (such as through a STRING terminal), an unresolved cross-reference produces a diagnostic message that includes the literal ref text. When a Sprotty diagram is opened for a malicious source file under these conditions, and a user hovers over the corresponding error marker, attacker-controlled JavaScript can execute in the browser or webview.8h CVE-2025-10248—
